Soccer Power Index: Daily update

ESPN's Soccer Power Index (SPI) is a rating system which uses historical data on both the international and club level to predict the outcome of a match. The algorithm uses several years of data, taking into account goals scored and allowed, quality of the lineup fielded, and the location of the match. In addition, SPI weights recent matches more heavily, and also takes into account the importance of the match, so a World Cup match counts much more than a Friendly.
